Test compression rate via following tools:
  1. Closure Compiler (2010/01/04)
  2. YUI Compressor 2.4.2 (2009/06/10)
  3. Microsoft Ajax Minifier 1.1 (2009/11/15)
Source file: jQuery 1.3.2 regular, jQuery 1.3.2 minified
jQuery 1.3.2 regularjQuery 1.3.2 minified
Original 124,99557,254
Closure Compiler (default) 55,334 55,334
Closure Compiler (advanced) 49,647 49,647
YUI Compressor57,524 56,705
Microsoft Ajax Minifier (default) 72,346 56,061
Microsoft Ajax Minifier (hypercrunching) 53,573 53,570

由上表可知,Closure Compiler不管source是否有經過其他方式壓縮,都能做出正確地壓縮,達成最小壓縮;贏家為:Closure Compiler


Conclusion: Closure Compiler can provide minimized javascript, it's the best choice!


2011 Update: Please take a look at UglifyJS – 更強大的 JS Compressor
